I Cleaned Rust from Bathroom Tiles with Vinegar. Now They're Hazy. How Do I Fix Them?

Q: Hi Apartment Therapy, I need your help. I had gotten rust on my porcelain tiles in my bathroom because of a metal Febreze bottle. I read that I could use vinegar to remove this and put a paper towel with vinegar over the stains. Now my tiles are hazy and I can't seem to fix it or find anything that is similar to my dilemma on the internet. They're new tiles and I'm worried because the rest of the floor is so shiny. Help! -Sent by Cheryl

Editor: Oh, man—to go from rusty to cloudy, that's no fun! Readers, how can Cheryl return the hazy tiles to their former shininess? And for future reference, what's the best way to remove rust stains from tile without clouding them? Thanks!
